Back and Forth in South America

For those of you keeping track, we entered and left the country of Argentina 3 times in 6 days.  We’ve spent only a few hours in Uruguay, Brazil, and finally left to go to Chile.  I now am going back into Argentina for the 4^th time in 10 days to visit the Mendoza valley, where I’ll study Spanish and hopefully drink a lot of Malbec.  The customs folks must wonder what I’m smoking.
